Here are some pics of my machine and the mechanism. I actually really like this machine. I'm not a bandit person, but assuming its just a Mills 10 stop mechanism.

Are these your videos? Or is the guy that makes them on the forum?

Afraid not, they are made by an enthusiast friend of mine who makes his contribution to the hobby. I'm sure he appreciates all supportive comments for his efforts. Much as we all appreciate his efforts!

I seem to recall that you have to unscrew a wooden bar to the left or right of the machine glass and the glass then slides out.

I have to say, when I got to the machine it was actually better than I’d thought. So agree with you that just doing something with the background is the way forward. Then the crisis is just where I can find a place for it!

Apologies for slow reply. Here are pictures of my machine.
